v0.6.5

Added

• A per-spec summary above the Checks/Evidence drill-down. The detail
  view went straight from the timeline to the Checks and Evidence tabs,
  which render every run's events/tokens/failing-checks line by line —
  nothing answered "how much has this feature cost, which gates has it
  exercised, is anything currently failing" without reading down through
  however many runs a spec has accumulated. A new summary section between
  the timeline and the tabs shows runs/tokens/events totalled across the
  spec's whole history, an "open fails" count scoped to the spec's own
  G0/G1 plus the latest run only (so a spec passing now doesn't read as
  failing because an earlier attempt once did), and one badge per gate id
  the spec has ever produced a result for, coloured by that gate's latest
  verdict. The Checks/Evidence tabs are unchanged — the summary is what to
  read first, the tabs are still where to drill in. Built entirely from data
  /api/overview already serves; no wire-format change.
